Abstract This chapter is intended to be a brief yet broad introduction to biomedical sensors and their underlying sensing mechanisms. The topics covered in this chapter include the classification of sensors, their sensing principles and modalities, and future trends in biomedical sensing devices. Sensors that use electrical transducing effects, such as thermoresistive, thermoelectric, piezoelectric, photovoltaic, electromagnetic, and electrostatic, will not be discussed in detail. It is discussed in the chapter entitled “Biomedical Transducer.” The objective of this chapter is to equip the readers with a general knowledge of biomedical sensors.
